Analyst Nick McQuire, from CCS Insight, told the BBC this could affect people’s trust in Microsoft.

“Microsoft wants to encourage people to update quite often,” he said.

“They have the facility to push down updates quickly, but this goes to show there is going to be continued resistance from users to download the latest and greatest update if they can’t ensure their quality control.

“They need to build trust with the community.”

Dona Sarkar, head of the Windows Insider Programme, tweeted that support staff “have the tools to get you back to a good state”.

Had the issue of missing files, not on MY computer, but my daughters’ PC. Called Microsoft Canada for support. His best solution: take it to the nearest Microsoft Store. In Toronto. Or Syracuse NY. I’m in Ottawa. I don’t drive. Not gonna happen. @brandonleblanc#windowsinsiders
